Preheat your oven to 350°F (175°C) and prepare your baking sheets by lining them with parchment paper or leaving them ungreased.

In a large mixing bowl, combine softened margarine and white sugar. Beat until light and fluffy, about 3-4 minutes.

Add eggs one at a time, mixing well after each. Stir in the vanilla extract until creamy.

In a separate bowl, whisk together the flour, baking powder, and salt.

Gradually add the dry mixture to the creamed butter mixture, stirring until just combined.

Roll dough into 1-inch balls and place on baking sheets, spacing them 2 inches apart. Flatten slightly.

Sprinkle red and green sugar sprinkles on top of each cookie.

Bake for 8-10 minutes until edges are set and centers are soft and slightly puffed.

Cool on sheets for a few minutes before transferring to wire racks to cool completely.
